Question

Write an equation in point-slope form for the given point and slope: (-5,-7); m=-7

Answer 1

y + 7 = -7(x + 5)

Explanation:

Point-slope form is
`y - y_(1) = m(x - x_(1) )`

y1= -7 , x1= -5

Substitute (-5,-7) and m=-7 into the equation

y - ( -7) = -7(x - (-5))

y - ( -7) = -7(x + 5)

y + 7 = -7(x + 5)
